Abstract: ABSTRACT OF THE DISCLOSURE            A thin film optical filter having a bandpass reflectance characteristic with one of the transition wavelength edges thereof being non-polarizing for radiation incident at a preselected non-normal angle.  The filter comprises a transparent substrate and a multilayer thin film optical coating provided on one surface thereof.  The optical coating includes a preselected number of alternate layers of a first higher refractive index dielectric material and a second lower refractive index dielectric material arranged as a sequence of dielectric multilayer stacks with interven-ing spacer layers formed of one of the dielectric materials. The optical thickness of the spacer layers is detuned from half-wave optical thickness to shift either the low wave-length transition edges or the high wavelength transition edges for the separate bandpass response characteristics for the two principal polarization planes substantially into alignment with each other.  Various other dielectric stack designs utilizing detuned layers to accomplish the same alignment of wavelength transition edges are described. Simplex and duplex fiber optic communications systems utilizing non-polarizing edge filters of the thin film type are also disclosed.

Abstract: ABSTRACT      A kiln plant for burning raw materials such as cement raw materials and the like includes a single-string, multi-stage suspension preheater, a suspension precalciner, a rotary kiln and a cooler.  The single-string preheater includes at least a lowermost preheater stage and a penulti-mate preheater stage each having a gas flow inlet and outlet.  The precalciner gas outlet is coupled to the gas inlet of the penultimate preheater stage.  The gas outlet of the lowermost preheater stage is also coupled to the gas inlet of the penultimate preheater stage.  The materials are precalcined in the precalciner solely by means of spent cooler air from the cooler while the materials are preheated in the lowermost preheater stage solely by means of kiln exhaust gases.  The pressure drops arising in the two gas flows through the precalciner and the lowermost preheater stage are equalized before the union of the two gases flows entering the gas inlet of the penultimate preheater stage.    The equalization of the pressure drops in the two gas flows is provided by a movable damper mounted in the respective gas flow duct before the juncture in the duct which permits the union of the two gas flows.  Preferably, the two gas flows are equalized so that the pressure drop across the precalciner is of the order of twice the pressure drop through the kiln and lowermost preheater stage.  A method of practicing the present invention is also disclosed.

Abstract: Précis La présente solution s'applique aux moteurs on géné-ral, de même qu' ux compresseurs.  Elle consiste à rendre étan-che la part?? cylindrée d'un moteur ou d'un compresseur par rapport à celle qui constitue plus spécifiquement le bloc. Ce résultat est obtenu par l'ajout d'une cloison entre ces deux parties du moteur ou du compresseur,cloison à l'inté-rieur de laquelle un conduit permet seulement à la bielle de circuler.             L'étanchéité ainsi produite du cylindre par rapport au bloc du moteur a tout d'abord l'avantage de rendre les mo-teurs à quatre temps plus économes on consommation d'huiles de lubrification,et a ensuite la propriété de permettre la construction d'un moteur à deux temps dont le combustible est séparé des huiles de lubrification, comme cela se produit dans les moteurs à quatre temps.       Dernièrement,appliquée aux compresseurs,elle permet de se servir du mouvement descendant du piston vers la cloison afin de compresser la gaz.
